For enhanced evaporator capacity, system stability, compressor protection and oil return.

Nominal SLHE selections should be based on system horsepower, which will provide a nominal 10ºF subcooling and a nominal 20ºF suction superheat for R-22, R-502, R-404A, R-507, R-407A, R-504, R-134A, R-407C and R-410A at 110ºF condensing and 25ºF suction. For example, for a 1-1/2 HP system, select an SLHE 1-1/2. Do not select undersized models to avoid high suction pressure drops and gas whistling.

Selections based on suction and liquid line sizes are appropriate for standard low, medium and high temperature refrigeration systems provided the system HP rating closely matches the SLHE selection.
